Sure it is - the problem is what do you use as the parent in the thread, when 
every message ID in the thread is listed?  KMail's problem is that it's using 
the first one - which is a valid interpretation of RFC2822, imo - but would 
work better if it used the last.  Or, if it can't figure out a single parent 
from In-Reply-To, use the References header - however, this isn't guaranteed 
because mailer's are permitted to truncate References at any size, and they 
aren't required to truncate oldest first.

I'll file a bug report against KMail, because the behaviour could be better, 
but it's only necessary because Windows Mail is misbehaving.
